Special multielement long-acting compound fertilizer for citrus

Abstract

The invention relates to a special multielement long-acting compound fertilizer for citrus. The compound fertilizer comprises following components: 40-50% of nitrogen, 15-20% of phosphorus oxide, 10-15% of potassium oxide, 0.03-0.05% of zinc, 0.003-0.005% of molybdenum, 5-8% of ammonium sulfate, and 20-40% of water hyacinth leavening, preferably, the content of ammonium sulfate is 6%. The compound fertilizer is rich in organic matters, the content of the organic matters is over 20%, humic acid in the organic matters has a good acid-base buffering effect, can effectively improve the soil granular structure, improves exchange capacity of soil cations, regulates soil pH value, improves water retention performance of the soil, can stimulate the activity of the soil enzyme and reproduction of beneficial microorganism, improves the soil fertility structure, can effectively improve the activity of nutrient elements, and is superior to a single compound fertilizer in effect.

Description

technical field [0001] The invention relates to a compound fertilizer, in particular to a multi-component long-acting compound fertilizer special for citrus. Background technique [0002] Citrus commonly used ternary compound fertilizer N-P-K = 15-15-15 wastes a lot of phosphorus and potassium. The growth of citrus has different requirements for the three elements N, P, and K, and plants can supplement some elements such as phosphorus and potassium by absorbing minerals in the soil. Studies have found that the basic fertilizers currently used on a large scale Released ternary compound fertilizers have a high cost. When the demand for nitrogen fertilizer is guaranteed, there will be excess waste of phosphorus and potassium, and phosphorus is the most significant. In serious cases, there will be green algae outbreaks in orange orchard soil and water sources, increasing non-point source pollution. The scope and extent are neither economical nor environmentally friendly. ...
